Abstract
This study arose from the need to control noise in naval vessels to reduce their detectability and hence vulnerability to enemy attack. In this report a detailed review of sensor and actuator technologies that could be used for active noise and vibration control in ship structures has been provided. The review focused on a wide range of sensor and actuator materials, such as piezoelectric and electrostrictive materials; magnetostrictive materials; shape memory alloys (SMAs); optical fibers; electrorheological and magnetoeheological fluids; microphones; loudspeakers; electrodynamic actuators; and hydraulic and pneumatic actuators. The diesel engine noise problem was the focus of the study, and consideration was given to the noise transmission paths, namely, the engine mounting system; the exhaust stacks and piping systems; the drive shafts and mechanical couplings; and the air borne radiated noise. Sensor and actuator technologies that are suitable for active control of noise through these paths (or similar structural systems) were reviewed. Based on factors, such as cost, frequency of the disturbance, the operating (marine) environment, experience in other applications, ease of implementation, and the expected performance, detailed recommendations on sensors and actuators for the paths were provided.
